I would fund higher education and healthcare, legitimate healthcare, not just the symptom chasing kind that makes billions in profits for pharmaceutical manufacturers. I think preventative care and focusing on health would reduce health care costs due to preventable conditions.
Education would also be a plus. So many young people graduating with debt up to their eyeballs and not enough decent jobs to go around. It's a sad situation. Fund higher education and remove tax incentives to companies who export jobs overseas and give them instead to companies who employ people here (at a living wage).
So many things I would do differently if I were in charge of the money lol :)
